One of Lilly's most impudent attempts to avail himself of demoniacal assistance was when he dug for treasure (like Scott's Dousterswivel) with David Ramsay (Scott again), one stormy night, in the cloisters at Westminster.

"Davy Ramsay," says the arch rogue, "his majesty's clockmaker, had been informed that there was a great quantity of treasure buried in the cloisters of Westminster Abbey; he acquaints Dean Williams therewith, who was also then Bishop of Lincoln; the dean gave him liberty to search after it, with this proviso, that if any was discovered his church should have a share of it. Davy Ramsay finds out one John Scott,[4] who pretended the use of the Mosaical rods, to assist him therein. I was desired to join with him, unto which I consented. One winter's night Davy Ramsay,[5] with several gentlemen, myself, and Scott, entered the cloisters; upon the west side of the cloisters the rods turned one over another, an argument that the treasure was there. The labourers digged at least six feet deep, and then we met with a coffin, but in regard it was not heavy, we did not open, which we afterwards much repented. From the cloisters we went into the abbey church, where upon a sudden (there being no wind when we began) so fierce, so high, so blustering and loud a wind did rise, that we verily believed the west-end of the church would have fallen upon us; our rods would not move at all; the candles and torches, all but one, were extinguished, or burned very dimly. John Scott, my partner, was amazed, looked pale, knew not what to think or do, until I gave directions and command to dismiss the demons, which when done all was quiet again, and each man returned unto his lodging late, about twelve o'clock at night. I could never since be induced to join with any in such-like actions.

"The true miscarriage of the business was by reason of so many people being present at the operation, for there was about thirty--some laughing, others deriding us; so that if we had not dismissed the demons, I believe most part of the abbey church had been blown down. Secrecy and intelligent operators, with a strong confidence and knowledge of what they are doing, are best for this work."
